While we now have scroll-wheels, wireless connections and touch-surfaces, the basic form factor of the computer mouse remains remarkably similar to the box-with-a-button first demonstrated by Douglas C. Engelbart back in 1968. This doesn't mean there haven't been attempts to shake-up mouse design though, and the latest to cross our desk is the Mycestro 3D mouse – a thumb-activated, wireless mouse that attaches to your index finger.
